Question

define inertia..??¿???​

Answer 1

Answer:

Inertia is a word we use when we talk about matter and movement. Basically, our idea of inertia goes back to Sir Issac Newton's first two laws of physics:

• 1. An object at rest tends to stay at rest.

• 2. An object in motion tends to stay in motion.

Inertia is the quality in matter (matter is anything you can touch) that lets it stay still if it is still, or keeps it moving if it is moving.

If you want to overcome inertia, you have to apply a force. A force will make something that is still start to move, like flicking a wad of paper with a pencil will make it move. Also force, due to resistance, will slow or stop something that is already moving. The wad of paper will be slowed by resistance made by rubbing up against the air it is passing through.

Answer 2

Answer:

a property of matter by which it continues in its

existing state of rest or uniform motion in a

straight line, unless that state is changed by an

external force.
